    I bought this UPS to serve as a backup for a single PC. The monitor and any other devices will be on a separate unit in another room so I did not need a large unit with a bigger battery. So far the unit has functioned but to be honest it does feel a little cheap when compared to competing brands I've purchased in the past. Only time will tell if it is reliable.

    Does what it is supposed to do. I only have switches and routers on this backup. But no issues during outages.

    This is my second CyberPower backup battery. I had the first one for what seems like ages before it finally would not hold a charge. I live in an older house (early 1950's) and get a lot of power flucuations/outages during thunderstorms. This unit is perfect for keeping my cable box and TiVo powered during short outages so they don't turn off and then have to reboot.

    I had some concerns that this relatively low-power UPS wouldn't support my large tower system, but it's doing fine. I only need enough power to keep my system from crashing during very transient power outages, and also to give me enough time to shut the whole thing down if the outage is a longer one. This gizmo works on both counts, and all for a total outlay of only $45 plus tax. Remember when these things cost hundreds?

    Not as expensive, but does the job.

    Purchased this to serve as both a batter back-up in case of a power outage, but also as a surge protector. Note that if you need a Data port, this will not work. My old printer uses a data line that does not fit with this, but we have another printer that we purchased at Christmas time that we primarily use anyway.

    This UPS is great for the price. The plugs are far enough apart to handle several bricks.

    I have several of these cyber power battery back ups. I bought the last one because I got a new 27 inch iMac. The imac is the only thing plugged into it so it last a long time. We live in a rural area an get a lot of split second power outages. It is like some one is in the garage flipping breakers. This is really hard on my electronics. If it would just go and stay out for a few minutes it would not be so bad. The momentary disruption is brutal on all electronic equipment. With cyber power I never lose power I get a constant 115 volts with no spikes and dips. That is what you want for sensitive equipment.

    I have had battery backup on both my computer and TV for several years. It's not foolproof against a direct lightning hit, but during summer storms it's a Godsend. And when we have those many power blips and spikes, they have protected equipment and data. This unit is not as heavy duty as the last, but it serves the purpose and was less expensive.

    Easy to install and use. Had a lightning storm roll on buy and it protected my electronics during the brown-out. Like it so much, I went back and bought another one. Good price for the product. If you but this device, don't forget to register it right away. :)

    Bought this just to protect my wireless router since the last one was damaged by lightning. The 1st one I brought home didn't work at all. The store swapped it out for another identical model and this one has been working fine.

    I wanted something that could give me a battery back up/surge protector so I could hook my cable box & modem up to for those occasional power surges here in Florida. I was told there wasn't anything that could handle he cable box (not sure I believe that), so I went with this one for the modem only, so far so good, seems to be able to handle it, but I still have to wait and watch my cable box reboot everytime.
